Description of the .Accompli :tying Drawings. Figure 1 is a perspective of a picking-machine,4 show- 'ing my invention attached, and the manner of attaching it.

Figure v2 is an under-side view of the plate, shotv ing the manner'in Whichit 4is prepared when vnot used in' a smooth state. y Figure 3 is a section of the plate, showing the teeth of the same when notused in a smooth'state.

Figure 4 is the spring used in adjusting thel plate.

Figure' is the nut, which` screws upon the bolt or post above the spring.

Figure 6- is the bolt or post, which passes through the `corners of the plate. i

Gene/ralv Description.

A is a concave section or plate, constructedv of iron, or anequivalent material, and of a size to suit the dimensions of the machine to whichit is to beattached. Y i v The plate A is placed' close to the picker-cap orv bonnet B, and held over the cylinder E by means of four bolts orposts O, which pass loosely through the corners of the plate, ,and are'fastened to the frame of the machine D by means of screws, or otherwise, as at G. Each holt is provided with nuts below the plate, las at F, by means of which the vplate A can rest upon the frame ofthe machine, `orbe adjusted labove it.

Above the plate there'is placed, upon each post, a. spiral spring, H, whichv is kept in place and adiusted by'means of nuts 'screwed upon the tops of the posts, as at J. Said springs keep the plate in its position -near to the picker-teeth, or allow it to, yield to any pressure from beneath, by moving up and down on tlleposts.

As the cylinder revolves, substances passing through `the machine, and not 'suitable forsfabrcs, instead of being thrown upward intothe air, assoon as released from'fthe cap, and falling back upon the machine, are carried alongby the plate of the guard until they reach the openingrbetweeuK and L, through which they are thrown entirely outside of the machine. Substances of a soft nature',are caught by the teethor roughness on the ,under side of the ,plate A, rolled up into wads or balls, by the motion of the cylinder, until thevplatc yields to the pressure, and allows them Yto escape, and the,centrifugal force throws them beyond the machine. 'p

I do not claim the machine, or any part thereof,

otherthan the attachment, as above described.

I claim, as my invention-,-

The yielding spring concavesec'tion or plate A, having its under side made smooth, rough, or vwith teeth, and applied and operating `in connection with the picking-cylinder, ,substantially as and for the purpose set forth.

GRAS.. I. DEAN.
